FUMIZING MABTIFQLD FOR ICITERIJAL-CUMBUSTTQET Application filed April 4,

.To all whom may concern:

Be it known that l, WILLIAMiMAR'rIN, a citizen of the United States of America, residing at Detroit, in the countgs of Wayne and State of Michigan, have invented certain new and useful Improvements in Fuelizing Manifolds for internal-Combustion Engines, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to manifolds for internal combustion engines and consists in the novel construction of a combination intake and exhaust manifold constituting a fuelizer for forming a combustible mixture from relatively low grade fuels. The invention further consists in. various features of construction as hereinafter set forth.

In the drawings:

Figure l is a side elevation of the manifold;

Figure 2 is an end elevation thereof;

Figure 3 is a cross-section on line 3---3 of Figure 1; v

Figure 4: is a vertical section on line t lof Figure 3.

My improvement is designed for use as a replacement for the intake and exhaust manifolds of internal combustion engines and to this end it is designed to conform generally to the lines of the manifolds replaced. As specifically shown, A is an 1ntegral casting having an exhaust manifold portion B and an intake manifold portion C, said ortions. being provided with the aperture bosses D, D, etc, for connection with the intalte and exhaust ports in the engine block. .The portion B formed with on opening in its front extending longitudinally thereof and surrounded by a flange or bearing forming a seat for a cover plate E. This cover plate is provided with the integral inward hollow projection F, which at its opposite ends is provided with inwardly ex tending annular flanges F forming a seat or bearing for an inner tube G, thereby forming an annular space between said. inner tube and outer walls The ends of the tubes are welded or otherwise integrated, resulting in an open ended tube located within the exhaust conduit in the path of the exhaust gases, the walls of said tube being chambered to form in efiect a retort. The cover plate E is further provided with integral hollow members I and J communicating with the annular space at opposite Specification of Letters Patent Pafigrgmfggqi Aug @319 j $2$ 1921. Serial 1%. states.

ends thereof. The member I forms an elbow fitting for connection with the downwardly extending conduit K and the member J has formed integral therewith the hollow cylindrical casings L and M having their axes perpendicular to each other. The portion M is formed with an elbow turn which fits against an apertured boss N in the intake portion C, while a stud O engaging said elbow and extending inward passes through the member C and forms a clamping means for securing theportion M thereto. The plate E is also secured to the member Aby tap screws P or other securing device, and there screws together with the stud O firmly secure the two castings to each other.

The fuel which is used in forming the enplosive mixture is controlled by a float chance her Q, which is preferably mounted upon a downturned arm R on the member t). This arm may, if desired, be hollow, but there is no connection between the space within the the arm and the float chamber, the only function being that of a mechanical support. S is a casing tormedintegral with the float chamber Q and connected therewith by the discharge passage S. This casing has its upper end connected by the packing gland S with the conduit K and into this conduit projects the upwardly extending discharge nozzle T, the lower end of which is in communication with the liquid fuel entering through the passage S. S is a drain plug for closing thelower end of the casing S and permitting of removing sediment or water which may collect in the casing from the fuel supply. U is a port in the upper part of the casing S communicating with the conduit K and providing for the admission of air Ehepeto to be commingled with the liquid The casing M forms a mixing chamber for vaporized fuel received from the retort and a proportionate quantit of air, the mixture being discharged directly into'th'e intake Inamfold C. The mixture is controlled by a sleeve valve V within the end of the cylindrical casing M, which is ported to re ister with an annular series of ports V H1 said casing. The valve is further provided with an elongated port W connected to a tube W extending inward within the sleeve and turned to discharge axiallyof the casing M. The port W is maintained in registration with the port connecting the casings L and M, the former being a valve casing in starting,

for plug valve X. This plug val'veis a threeway valve which is ported so that in one position it establishes communication between the casing" M and the conduit d, while in another position cuts ofi such communication. and; connects the casing M with an auxiliary fuel su ply Y suitable for use With the construction as described, in

operation, the suction. formed in the intake C is communicated to the casing and from the latter either the retort or to the auxiliary incl supply according to the position of adjustment of the valve X, In starting, this valve X is so turned that supply of the auxiliary fuel, such as gasoline, is directed into the chamber M, where it is commingled with air entering through the ports V This will form an explosive mixture which will start the engine and as soon as the manifold is suiiicient warmed, the valve X is adjusted to its other position, Where the auxiliary fuel supply is' cut ofi and communication is established between the chamber M and, the conduit J, This adjustment of: the valve may be accomplished b a' suitable connection such as the lever 1 and rod X leading to a point under the control of the operator.

When the valve X is adjusted in the position last-mentioned, the suction of the on.

gine is communicated to the retort formed by the hollow member F and through the latter to the conduit K and casin S. This will cause the discharge of the ow grade fuel from the nozzle T into the conduit K and at the same time air drawn in through the port U will commingle with the discharged liquid and form a vehicle for carrying it into the retort. During passage through the retort the fuel is vaporized so that a rich. mixture of fuel vapor and a small amount of air is discharged into the casing M. Here a further supply of air isadmitted through the ports V, resulting in the proper mixture for combustion.

The construction is comparatively simple as it is formed in the main of three castings; first, the member A with the integral exhaust manifold and intake portionsB and C and supporting arm R; second, the cover member E with the integral retort and inlet and outlet connections, the latter including the valve casing L and the mixing chamber N; and third, the float chamber Q with the integral casin S containing the discharge nozzle T. n addition to these parts, there are only the valves, pipe connections and control levers and the whole construction forms a unit assembly which can be readily attachedto the engine block as a replacement for the standard inlet and exhaust manifolds.
